Chapter Ninety-Nine: The Thermometer

Su You said with a smile: "These are all things that I made myself, and they are different from spending money to buy them, so I can't say that they are extravagant and wasteful." ”

Shi Fu nodded: "Yes, Bagong, you can bear it with peace of mind, this is all made by Xiaoyou himself, he should do this filial piety." ”

Bagong still chose osmanthus wine, and used a small bamboo grape and a small porcelain funnel to carry a jade porcelain bottle and put it on the table: "This wine vessel is also exquisite, hehehe, don't look at the small bottle and the small cup, if you don't pay attention, you will drink high." ”

Shi Wei looked at the cute little porcelain cup: "Uncle Su, I want to drink it too." ”

Hachiko said: "Children can't drink this, go boil some mash water with little oil, you two drink it." ”

Shi Fu took the wine bottle and poured it for Shi Wei: "Daughter Jiangmen, a glass of spirits is nothing." ”

Su You was cheeky: "Then I'll also accompany Wei'er for a drink." ”

Hachiko scolded: "I'm afraid that Wei'er is also picked up by you, right?" ”

Shi Fu also added a glass to Su You: "The wine is all made by him, can you still prevent it?" I'm afraid that this kid hasn't drunk less when he tastes wine! ”

Su You was not convinced: "Am I calling for drinking?" There are no dishes, I call it quality monitoring! ”

Shi Fu and Shi Tong couldn't help laughing, and Hachiko also laughed angrily: "I can't control you, I can only have one cup." ”

Everyone walked together, and Wei'er took a sip: "Osmanthus is so fragrant......"

Shi Fu was very happy: "Look, I said Wei'er is amazing, right?" No problem at all. ”

Su You said: "Wine is indeed a good thing, use alcohol to disinfect the wounds of the castrated little roosters, and the little roosters are stunned that none of them are dead." ”

Shi Tong then remembered: "Shi Da asked me to bring something, saying that you asked him to make it, I heard that it is related to this wine, and I almost forgot if you didn't mention it." ”

Su You said: "I've been so busy these days that even I forgot about it, this is an alcohol concentration meter, and there will be standards for good wine and wine in the future." Yongchun dew is so expensive, we have to let everyone know that there is a reason for it. ”

Shi Tong said: "Yes, it is like the so-called ratchet in the micrometer, which is actually realized by knurling on two copper sheets and a thin spring. It's a little different from the mechanical ratchet you drew before, Master. ”

Su You said: "It's called a force measuring mechanism, although the use and appearance are different, but in fact, it is also to control one-way rotation, and the principle is the same, so it is correct to make it a ratchet." “

"For example, the ball bearings used for folding knives and the ball bearings used for waterwheels are two things, one is to reduce the friction between the inner and outer rings, and the other is to reduce the friction between the upper and lower pieces, and the principle of reducing friction is the same, so they are called ball bearings."

Shi Tong sandwiched a large piece of back to the pot and put it in his mouth: "I understand, Master, with a manual stamping machine and a micrometer, I believe that this time I can make a qualified small ball, and next time I will bring the finished product to you for tasting!" ”

Su You said with a smile: "You said it simply, it's easy to make small balls, but it's difficult to make small balls with exactly the same caliber. It's early! ”

"After you understand the various mechanical principles and geometric motion trajectory, you will be able to design the machinery by yourself, and you will strive to improve the pass rate as soon as possible."

After speaking, he thought about it again: "Bearings, slides, are really useful to my Da Song, and the key to them is the ball." To refine the balls, it is necessary to use the ball grinding equipment to improve the yield. And the ball grinding machine involves an interesting mathematical phenomenon, so tomorrow we will continue the class and talk about this thing. ”

Shi Wei said: "Clockwork is also very useful! Shi Tong, did you bring me a clockwork? Brother Xiaoyou took my golden toad's clockwork to make a thermometer. ”

Shi Tong patted his chest and packed the ticket: "Bring it, aunt and grandmother, don't worry, I'll take care of it for you after eating, and the golden toad that takes care of you can be alive again!" ”

After eating, Shi Tong reloaded Shi Wei with the golden toad, and then began to hang the thermometer.

The design of Su oil and the craftsmanship of Shijia Iron Workshop make the new thermometer much more beautiful.

A clock-like dial with all the mechanisms below the dial and only a thin copper disc on the dial.

Underneath the copper plate is a stamped pattern, and an old master bends down and talks to two children, one of whom points to the sun in the sky.

This is an allusion to Confucius and the two children arguing about the day, taking the text "The beginning of the day is cool and cool, and the middle of the day is like exploring the soup, this is not hot for the near and cold for the far?" The meaning of ".

With this thing decorating, an ordinary cold and summer watch immediately became extremely tall.

There is a fan scale above the disc, as well as a thin hand.

The cold and summer watch was hung on the wall outside the hall, and Hachiko looked at it for a long time with his hands behind his back: "Beautiful, the degree on it is thirteen, right?" What does thirteen mean? ”

Su You is also very satisfied with this cold and summer watch, and said with a smile: "This is the cold and summer watch, which is roughly the temperature of water boiling 100 degrees, the temperature of water freezing is 0 degrees, and the temperature of Meishan is generally from a few degrees to 40 degrees, and now it is thirteen degrees, which is the normal temperature in early winter." ”

After speaking, he beckoned the stone to pass through: "If you want to sell this watch to Liaoguo in the future, the temperature below zero can be marked, and I heard that when it is cold over there, it can reach dozens of degrees below zero." ”

Shi Tong said angrily: "Lao Tzu's good things, I won't give them to Liao Dog if they are smashed!" ”

Su had to fly up and kick the stone: "Are you stupid, are you stupid!" If this thing can be exchanged for a few good horses, why don't we do it? Do you want to do it?! I'll kick you to death ...... fool."

Shi Tong was not ashamed but proud, and grinned: "Master, master, you finally call me an apprentice......

Su You put his hand on his head: "I can't talk to you with this big stone, Wei'er, let's go, let's get our concentration meter!" ”

The concentration meter is actually very simple, it is a small porcelain bottle with a sealed culet, followed by a thin porcelain tube, and the porcelain tube is hollow and communicates with the porcelain bottle.

Pour the very small porcelain beads into the porcelain bottle through the tube, adjust it to the porcelain bottle is completely submerged, and most of the porcelain tube can still be suspended on the water surface.

Then the water surface position at this time is zero degrees, and then put the tube into pure alcohol, the tube will sink a lot, and the scale obtained at this time is 100 degrees.

Then the question arises, what is used to mark the scale?

Alcohol is an effective solvent for most organic colors! I can't even carry the lacquer.

After thinking about it, Su You had to find a thin silk thread and wrap it around a few sections, and the boundary between the upper end of the silk thread and the porcelain tube indicates the degree.

With one to one hundred, there is only one equal division in between.

This degree does not need to be too precise, just tie a piece of silk thread every fifth degree.

The tube is a bit long, and Su You took two short tubes and made two alcohol concentration agents from zero to 50 degrees and 50 degrees to 100 degrees respectively.

In fact, it is very simple to solve the scale problem, the concentration meter of later generations, the glass tube directly used, stuffed with a paper strip with a scale, how can the liquid not be immersed.

Glass...... Well, it's not that hard.

But there are a lot of things, if it's not something that is urgently needed, take your time, you can make do with it anyway, Su You clapped his hands and said to Shi Wei: "No way, now it's the only way." ”

Shi Wei is also immersed in the magical buoyancy world: "Brother Xiaoyou is so powerful......"

Su You smiled, the brainless fan is what you look like, and couldn't help touching Shi Wei's head: "You understand what is amazing?" I'll tell you the truth about it another day, now let's play the music box first, and Shi Da brought a few more songs. ”

The drum in the music box is replaceable, and the small teeth on the drum will make a tinkling music when they pluck the steel plate, and one drum is responsible for one song.

The first box is the music "Farewell" in later generations, the one on the ancient road outside the long pavilion, but now these songs are weird, and Su You can't understand it.

Shi Tong was proud: "I found out!" Master, you are interested in music, painting, and chess...... It's all laymen! Last time you had a box, the rhythm was not right! ”

Traditional Chinese classical music is somewhat different from the Western music of later generations, with five positive tones and two diacritics, among which the changing signs and changing the palace are the hair and west in the later Western music, which were rarely used by the ancients.

Su You looked at Shi Tong with disdain: "It's not right to use the change sign and change the palace?" This world is complicated, and you can only use the correct tone, which is your own level is too poor! ”
